Copper Toxicity Management
Symptoms and Diagnosis
- Copper toxicity can cause severe multi-organ damage including hematemesis, hypotension, melena, coma, headaches, behavioral changes, fever, diarrhea, abdominal cramps, Kayser-Fleischer rings in the eyes, and jaundice, requiring prompt treatment with chelating agents such as D-penicillamine 1, 2
- Hematemesis (vomiting blood) is a symptom of copper toxicity 1
- Melena (black "tarry" feces) is a symptom of copper toxicity 1
- Diarrhea and abdominal cramps are symptoms of copper toxicity 1
- Headaches and behavioral changes are symptoms of copper toxicity 1
- Coma can occur in severe cases of copper toxicity 1
- Neurological deterioration can occur in copper toxicity 3
- Hypotension is a symptom of copper toxicity 1
- Jaundice is a symptom of copper toxicity 1
- Liver failure (often the first organ affected) can occur in copper toxicity 1
- Hemolytic anemia can occur in copper toxicity 3
- Coagulopathy unresponsive to vitamin K can occur in copper toxicity 3
- Kayser-Fleischer rings (brown ring-shaped markings in eyes) are a pathognomonic finding in copper toxicity 1, 3
- Fever is a symptom of copper toxicity 1
- Measurement of serum copper and ceruloplasmin levels is used in the diagnosis of copper toxicity 3
- CRP determination is used to differentiate copper toxicity from inflammatory conditions 1
- Liver function tests are used in the diagnosis of copper toxicity 3
- Slit-lamp examination for Kayser-Fleischer rings is used in the diagnosis of copper toxicity 3
- 24-hour urinary copper measurement is used in the diagnosis of copper toxicity 3
Treatment Approach
- D-penicillamine (250-500 mg/day initially, then increased by 250 mg increments every 4-7 days to a maximum of 1000-1500 mg daily in divided doses) is used in the treatment of copper toxicity 1
- Zinc administration (competes with copper for absorption) is used in the treatment of chronic copper toxicity 1, 3
- Lifelong therapy with copper chelating agents is used in the treatment of Wilson's disease 3
- Regular monitoring of copper levels is essential in the treatment of copper toxicity 3
- Liver transplantation may be considered in severe cases of Wilson's disease 3
- First-degree relatives of patients with Wilson's disease should be screened 3
- Regular monitoring of liver and renal function is essential in the follow-up of copper toxicity 3
- Periodic measurement of serum copper levels is essential in the follow-up of copper toxicity 3
- In patients on parenteral nutrition, copper levels should be checked every 6-12 months 1
